PREV DISCUSSION... /ISSUED 455 PM CDT TUE APR 2 2013/

SYNOPSIS...
LATEST UA ANALYSIS AND WV IMAGERY SHOWS AN UPPER LOW NR THE
NEV/COLO BORDER WITH DISTURBANCES EMANATING EASTWARD ACRS TX.
MOISTURE CONTINUES TO INCREASE FROM THE WEST WITH SHOWERS AND
THUNDERSTORMS...SOME STRONG...BECOMING MORE NUMEROUS ACRS PORTIONS
OF CNTL TX THIS AFTN. SEVERE THUNDERSTORM WATCHES HAVE RECENTLY
BEEN ISSUED ACRS PORTIONS OF THAT AREA...UP TO OUR WRN BORDER.
CLOSER TO OUR AREA...KLCH RADAR DEPICTS JUST SOME ISOLATED LT RAIN
SHOWERS ACRS SWRN LA AND SE TX. A WEAK SFC FRONT EXTENDS NW TO SE
ACRS THE CWA...NR OR JUST NORTH OF A LINE FROM LUFKIN TO
PATTERSON. DESPITE ABUNDANT CLOUDS ACRS MUCH OF THE AREA...AFTN
TEMPS HAVE WARMED INTO THE MIDDLE AND UPPER 70S.

DISCUSSION...
RAIN CHANCES WILL INCREASE TONIGHT INTO WEDNESDAY AS THE UPR LOW
MOVES INTO THE SRN PLAINS. THE STORMS ACRS CNTL TX WILL CONTINUE
TO MOVE EAST...BUT THINK THAT ACTIVITY WILL WEAKEN AS IT GETS
CLOSER TO OUR AREA. THE SFC FRONT WILL CONTINUE TO SAG SLOWLY
SOUTH TOWARD THE COASTAL WATERS TONIGHT. SFC LOW PRES WILL DEVELOP
ALONG THE WRN FLANK OF THE FRONT NR THE MIDDLE TX COAST BY
WEDNESDAY MORNING. DECENT ATMOSPHERIC MOISTURE IN PLACE AHEAD OF
THIS SYSTEM...WITH PW VALUES BETWEEN 1.5-1.7 INCHES. WIDESPREAD
SHOWERS WILL AFFECT THE AREA WEDNESDAY...WITH SCT THUNDERSTORMS
POSSIBLE MAINLY ACRS THE SRN ZONES AND ADJACENT COASTAL AREAS.

PRIMARY CONCERNS FOR THIS AREA WILL BE THE POSSIBILITY OF HEAVY
RAINFALL AND SEVERE WEATHER. HOWEVER...IT APPEARS NOW...AND MODELS
SEEM TO BE IN GOOD AGREEMENT...THAT THE SFC LOW WILL TRACK SOUTH
OF OUR LAND ZONES WEDNESDAY...CROSSING THROUGH OUR FAR SERN
COASTAL WATERS ZONE WEDNESDAY NIGHT. THIS WILL LIMIT THE POTENTIAL
FOR THE WARM SECTOR TO LIFT INLAND...LIMITING THE POSSIBILITY OF
SEVERE WEATHER AND KEEPING HIGHEST RAINFALL TOTALS OVER THE ERN
COASTAL WATERS. A LOOK AT FCST SOUNDINGS ACRS THE AREA SHOW DECENT
LOW LVL SHEAR...MAINLY OVER THE SERN ZONES...BUT ONLY MODEST
INSTABILITY. THUS THINK THE THREAT OF ANY STRONG TO SEVERE STORMS
WILL REMAIN MORE OFFSHORE...WITH JUST ISOLATED STRONG STORMS
POSSIBLE ACRS S CNTL LA WEDNESDAY AFTN. AVERAGE RAINFALL TOTALS OF
2 TO 4 INCHES WILL BE POSSIBLE FM TONIGHT THROUGH THURSDAY. SOME
LOCALLY HIGHER AMOUNTS WILL BE POSSIBLE IN HEAVIER SHOWERS AND
STORMS...BUT GIVEN THE RECENT DRY CONDITIONS...THE THREAT FOR
WIDESPREAD OR SIGNIFICANT FLOODING APPEARS LOW AT THIS TIME.

RAIN WILL END FM W TO E THURSDAY AS DRIER AND COOLER AIR MOVES
INTO THE AREA ON BUILDING HIGH PRESSURE. DRY WEATHER AND COOLER
THAN NORMAL TEMPERATURES ARE EXPECTED FROM THURSDAY THROUGH
SATURDAY MORNING. A WARMING TREND WILL BEGIN SATURDAY...WITH
HUMIDITY GRADUALLY INCREASING INTO EARLY NEXT WEEK AS THE SFC HIGH
SHIFTS EAST AND SLY WINDS DEVELOP. THE NEXT CHANCE FOR RAIN WILL
RETURN MONDAY INTO TUESDAY AS AN UPPER LVL TROF DIGS INTO THE
SWRN STATES AND MOVES EAST.

MARINE...
A MODERATE EASTERLY FLOW WILL PERSIST THROUGH WEDNESDAY AS A WEAK
COLD FRONT SLOWLY SHIFTS SOUTH INTO THE COASTAL WATERS. LOW
PRESSURE WILL DEVELOP ALONG THE MIDDLE TEXAS COAST BY WEDNESDAY
MORNING AND TRAVEL EAST OVER THE NORTHWEST GULF THROUGH THE
DAY...WITH A STRENGTHENING OFFSHORE FLOW DEVELOPING IN THE WAKE OF
THE LOW WEDNESDAY NIGHT INTO THURSDAY. WIDESPREAD SHOWERS AND
SCATTERED THUNDERSTORMS WILL ACCOMPANY THIS SYSTEM AS IT CROSSES
THE AREA...WITH ACTIVITY ENDING BY THURSDAY AFTERNOON. SMALL CRAFT
ADVISORY CONDITIONS WILL BE POSSIBLE THURSDAY INTO THURSDAY
NIGHT.
